These materials cannot safely be used by the inexperienced or those without basic knowledge of electronics.This is because:1. A rebuildable coil/wick MUST be tested carefully with a meter before it is used.2. If it is not tested it is entirely the risk of the user.3. Faulty wicks/coils WILL blow electronic devices.4. New coil/wick units must be tested and then used first on a strong basic electrical APV that has short circuit protection.5. No new coil/wick assembly should be used on an electronic device until known to be safe.6. These items destroy electronic devices if faulty. This is a known issue.
